Friction Folder Knife – DIY project approach..

Step 9: Final Assembly – Precision Epoxy Application:

The final assembly of your friction folder knife involves carefully disassembling, applying epoxy, and reassembling the components. Follow these detailed steps to ensure a secure and durable bond:

1. Disassemble the Knife:
   1. Carefully remove the pins or rivets to disassemble the knife.
   2. Keep track of each component to simplify the reassembly process.

2. Prepare the Surfaces:
   1. Thoroughly clean and degrease the mating surfaces of both the blade and the handle scales.
   2. Dry all surfaces thoroughly to help ensure the epoxy will bond effectively.

3. Apply Epoxy:
   1. Mix the epoxy according to the manufacturer’s instructions.
   2. Apply a small amount of epoxy to one of the handle scales.
   3. Use a toothpick or a small applicator to spread the epoxy evenly across the surface.

4. Reassemble the Knife:
   1. Place the blade between the handle scales, aligning the holes for the pins or rivets.
   2. Carefully insert the pins or rivets through the holes to secure the components together.
   3. Ensure that everything aligns perfectly.

5. Check Alignment:
   1. Before the epoxy starts to set, double-check the alignment of the blade within the handle.
   2. Verify that the blade can pivot smoothly and that the handle scales are flush against the blade.

6. Wipe Off Excess Epoxy:
   1. Use a clean cloth or cotton swab to wipe off any excess epoxy that may have squeezed out during reassembly.
   2. Thoroughly clean all residues as this is crucial for a clean and professional looking finish.

7. Secure in a Vise or Clamps:
   1. Once the knife is fully assembled, secure it in a vise or with clamps.
   2. This ensures that the components remain in place and that the epoxy cures under pressure for a stronger bond.

8. Allow Epoxy to Cure:
   1. Follow the epoxy manufacturer’s recommended curing time.
   2. This typically involves leaving the assembled knife undisturbed for several hours or overnight.
   3. Ensure that the environment is at the recommended temperature for optimal curing.
   4. Avoid excessive heat near any applied epoxy as it can destroy it’s ability to cure correctly.

9. Clean Up:
   1. After the epoxy has fully cured, remove the knife from the vise or clamps.
   2. Trim any excess pin material if needed and clean up any remaining epoxy residue using a fine abrasive or sandpaper.

10. Final Inspection:
    1. Inspect the knife for any imperfections or irregularities.
    2. Ensure that the blade opens and closes smoothly, and the handle is securely attached.
    3. Make any final adjustments if necessary.
    4. If Acetone is needed to make any corrective adjustments, restart assembly steps from the beginning…. Amen.. =/

By following a set of well planned, detailed steps, you help ensure a meticulous and precise final assembly of your friction folder knife. The use of epoxy provides a strong and durable bond between the handle scales and the blade, resulting in a professionally crafted and functional custom knife. With careful attention to detail and safety, you may be able to create your own handmade friction folder. A knife that could be showcased, or if intended, put to practical use.
